What They Say
The 8K Association published an article that followed up news through Gizmodochina that TCL’s CSOT operation has developed a 75″ 8K display that uses an amorphous backplane with a 1-gate/1-drain (1D1G) transistor design that is, nevertheless, capable of supporting 265Hz operation in 8K. Chris Chinnock of the 8K Association had posted a Display Daily back in May about that kind of design, but based on an IGZO backplane. The simpler architecture allows for a four mask process. (TCL CSOT Shows New 8K Panels and Technology).
The firm claims that transmittance has increased by 10% year on year. The version described in May was said to have 4.5% transmission, so it suggests closer to 5%, although May was, of course, not a year ago. The panel uses a gate-on-array architecture and a ‘China Star point to point interface, which is used for the signal encode/decode between T-con and driver IC’. It also has a unique “Horizontal Charge Control” (HCC) row variable charging technology.
What We Think
This is quite an achievement. 265Hz 8K operation is, in itself, a high level of performance and to achieve that using amorphous silicon is surprising. To be honest, I’m having a hard time getting my head around it! Then again, I have heard that the latest IGZO technology is heading towards the lower LTPS levels of performance. (BR)
